WannaCry, One of the Ransomware Attacks in 2017

WannaCry - a worldwide spread malware occurred on Windows 7/8/10/ XP, etc in May 2017 which is one of the ransomware attacks today and affected many organizations and companies via the vulnerability of Windows system.

Once your computer has been attacked, you can’t access any important files unless you pay 300 dollars worth of bitcoin at the time of infection. If you don’t, the ransom will increase to 600 dollars after three days. And seven days later, you will lose all your files if you still don’t pay it.

WannaCry Ramsome

The Influence of Ransomware WannaCry

Recently, you can hear ransomware WannaCry here and there. Thus, we need to be aware of its influence. In the event of ransomware WannaCry, the malicious people only use two NSA exploits, However, it leads to a great disturbance.

Up to now, the ransomware WannaCry has hit at least 150 countries including Britain, China, Russia, Germany, and Spain etc, and infected over 230,000 computers coming from hospitals, universities, manufacturers and government agencies, etc.

The Prime Targets of Ransomware Attack in 2017

From this experience, the prime targets of ransomware is an increasingly concerning question most people want to know. In this case, most of the attacked computer comes from hospitals, universities, manufacturers and government agencies, etc. Thus, there are some potential targets you need to know.

1. Any organization needs to access critical data every day. Because they can’t afford to be locked out of their data. At the same time, they are supposed to be the ones who will worry about ransomware the most. That’s to say, banks, hospitals, Congress, police departments, airlinesairports, etc are likely to be the victim of ransomware.

2. To a degree, any large corporation or government agency containing critical infrastructure is also at risk.

3. Individual computer sometimes is a target. If you can’t put a patch regularly for your computer or upgrade it to the latest version, you may be the next victim.

How does Ransomware Work?

On a webpage, you can see attackers take the security hole of the Windows system as a weapon to attack companies or organizations which need to access critical data every day.

Aside from that, some unnecessary ports like 445, 135, 137,139, etc are possible to be a way attackers may make full use of. You can choose to block port 445 or others in Windows.

Prevention Measures for WannaCry Ransomware or Similar Attack

When we encounter ransomware, here is WannaCry, we still can do something to solve it.

1. Don’t click these suspicious Emails and Links. We are possible to receive many emails containing links, if you are not sure the email is safe, you would better not click it. Because the email or links may contain a virus.

2. Install a ransomware attack patch on the computer. To security holes, you are supposed to put patches regularly. Because your important files or folders etc are stored on your computer. Once something bad happens, you will lose them forever. At the same time, running whitelisting software on machines can resist attacks to some extent since the lists won’t let your computer install anything that’s not already approved.

3. Install antivirus software. Antivirus software can detect viruses in a way. Thus, regularly checking your computer can reduce the possibility of a virus attack.

4. Block unnecessary ports 445 in Windows. In the computer, there are some unnecessary ports opened by the Windows system you need to close, including 445/135/137/139 on Windows 7, Windows 10, Windows XP, and Windows Server 2003/2008. If you don’t block them, malicious people may attack your computer via these ports.

5. Disconnect the computer. To against further infection, administrators will immediately disconnect infected systems from corporate network, and disable WiFi and Bluetooth on machines.

The Core Strategy to Prevent Data Loss Even in Ransomware

I'm sorry that even if you do all the above precautions, you still need to be careful. Because you only have one copy of the files and if your computer is attacked, you will lose your data again or pay a ransom, just like in WannaCry Ransomware.

  • The suspicious emails or links may become more and more complex and you cannot recognize them.
  • Sometimes, putting patches can be forgotten.
  • Antivirus software is not perfect, which may not recognize all the viruses.
  • ...

And, from this experience, we can clearly get that the Windows system is not perfect and malicious people may exploit security holes to attack our computers. So we can’t depend on it too much.

The best way to prevent it or similar errors is to follow the 3-2-1 backup strategies - keep 3 backup copies at least, on 2 different locations and one offsite. Thus, you will always have a copy of your files even if your computer is attacked. You need the help of the best free auto backup software - AOMEI Backupper Standard. With it, you can:

Backup files to external hard drive (HDD or SSD), USB drive, network drive or NAS, cloud drive like Google Drive, OneDrive, Dropbox, etc. 
Run backup task automatically with its schedule backup feature. You can use the daily, weekly, or monthly settings, if you change files frequently, you still be able to run it hourly under daily.
Keep track of only changed files with incremental backup to save backup time and disk space. Also, this software will compress backup image to smaller automatically, backup only used sectors of file system, etc.

To prevent data loss even in Ransomware, please AOMEI Backupper Standard and install it.
